A-type Sigma Models from Differential Poisson Geometry
Cesar Arias, Per Sundell
We study the differential Poisson sigma model (DPSM) in the symplectic case and show that its classical reduction defines a distinguished class of A-type models on symplectic targe…
Reconstructing the boundary of AdS from an infrared defect
Cesar Arias
We argue that the boundary of an asymptotically anti-de Sitter (AdS) space of dimension , say , can be locally reconstructed from a codimension-two defect located in…
Conformal Geometry of Embedded Manifolds with Boundary from Universal Holographic Formulae
Cesar Arias, A. Rod Gover, Andrew Waldron
For an embedded conformal hypersurface with boundary, we construct critical order local invariants and their canonically associated differential operators. These are obtained holog…
Liouville description of conical defects in dS, Gibbons-Hawking entropy as modular entropy, and dS holography
Cesar Arias, Felipe Diaz, Rodrigo Olea +1
We model the back-reaction of a static observer in four-dimensional de Sitter spacetime by means of a singular quotient. The set of fixed points of the …
De Sitter Space and Entanglement
Cesar Arias, Felipe Diaz, Per Sundell
We argue that the notion of entanglement in de Sitter space arises naturally from the non-trivial Lorentzian geometry of the spacetime manifold, which consists of two disconnected…
Einstein-AdS action, renormalized volume/area and holographic Renyi entropies
Giorgos Anastasiou, Ignacio J. Araya, Cesar Arias +1
We exhibit the equivalence between the renormalized volume of asymptotically anti-de Sitter (AAdS) Einstein manifolds in four and six dimensions, and their renormalized Euclidean b…
